Resin for 2000 degree carbon fiber plates?

General Composites Discussions Composites Talk
#1

Does anyone know what these guys use to make rigid cf plates that can withstand up to 2000 degrees?

I have never found any epoxy resin that can stand any more than 650 degrees at the very most…

Their plates look like regular 2x2 twill weave cf plates so whatever resin they are using, it’s clear in color.

I can’t find any resin of any type that could achieve this.

The parts are CFC, Carbon reinforced Carbon. That is something complete different to a epoxy part. The pictures where you can see the weave I would bet are standard carbon parts and not hear resistant.

I work with some BMI fiber glass that is good up to 600 degrees F. Though it’s pretty damn expensive… I think the per roll cost is something like $20k+

I can only imagine how expensive carbon carbon is…

They sell a number of 2000 degree resistant cf parts and all the pics show a twill appearance.

Name of the link kind of gives it away !
It’s ceramic carbon,mad material !!! The stuff I have used had a 15 minute out life,lay it down an bag up VERY quickly
200 degrees cure.
When being post cured you could open the oven up at 4/500 deg an pick the carbon part up an it didn’t retain heat

Is that stuff capable of withstanding 2,000 degrees for metal casting work?

#7

not the ceramic reinforced like SISIC but the CFC does. But be careful because it might choal up the metal!

The way those parts are advertised suggests that they can be used in a metal casting environment and withstand those 2000 degree furnaces. It would be shamefully misleading if they only meant the cf fabric and that the actual part would lose it’s shape as the resin failed.

If the intent is to mislead like that then it would be asking for trouble as it’s a recipe for a very nasty accident. People would lose their legs as liquid steel fell through a warped crucible and burnt through them.

Maybe they use some type of ceramic binder that can withstand a 2000 degree environment. I have never heard about any epoxy products getting anywhere close to that temp.
